As you may have noticed, the price of fuel is on the up. Obviously the knee-jerk reaction is to burn some sheep, organise an ineffectual ‘Don’t Drive Day’, or just sigh heavily. However, I have resolved to do something practical about it this time.

Previously I have got huffy and joined the Battery Vehicle Society a few times. I also looked into those on-board hydrodgen plants that cost £500, and those rather cheaper jam jar based ones that probably start to corrode your manifold and cylinder heads prematurely. Yes, I even read up about those daft magnets. Indeed, I was with a mechanic the other day when he found some on a E39 525i, and he couldn’t stop laughing.

Petrol prices set for record high

So although I am tempted to buy a cheap light car like the Perodua Nippa, make it lighter then reprogramme the ECU, put pizza plate hubcaps on and a teardrop tail, what I would really like to do is just convert an existing petrol engine so that I can drive a car I actually like.

Methane comes to mind and so does alcohol. Just like with LPG you start with a smidgen of petrol and then switch over to the homemade stuff.
